After reboot vasypd not responding to ypbind until it is restarted
说明
After reboot, vasypd is not serving map information until it is restarted
原因
ypserv and vasyp were both installed. vasypd starts up, registers for NIS. Then ypserv starts up, registers for NIS, breaking our register. Then on restart of vasypd it re-registers, and it begins to work again.
